1 How does the epros®DrainLCR-B work?

Leaking downpipes and sewers in buildings still typically mean bad smells for the residents and can, in the worst case, result in structural damage and moist walls or even mouldiness. Conventional repair methods – breaking up of walls and/or grounds – then make people suffer noise, dirt and service disruption. epros®DrainSystems by Trelleborg Pipe Seals Duisburg have a remedy for this problem: The new epros®DrainLCR-B repair method repairs laterals without breaking out walls or excavations, and thus means much less annoyance of residents. Trelleborg Pipe Seals Duisburg, one of the worlds’ leading specialists in innovative technologies for the upkeep of water and sewage systems, has been developing and selling efficient systems for trenchless repair and rehabilitation of infrastructures for more than 20 years. epros®DrainLCR-B is a pipe repair device or method for the rehabilitation of in-house downpipes and underground sewers. In this novel method, the repair unit is inserted in the existing access holes, chambers or eyes of the rainwater or wastewater downpipe and sewer and pushed to the point of repair by means of compressed-air push rods.

In the past, repairs from the inside of a vertical pipe were limited to either patch repairs or to the installation of full-length liners. Now, the epros®DrainLCR-B allows lateral branch connections to be repaired without the need to break out walls. For this purpose, the LCR-B packer is introduced in existing openings of rain or foul water pipes. As the LCR-B packer is highly flexible, it will smoothly negotiate 45° elbows in a DN 100 main pipe and even 90° elbows in lines of DN 125 or more. An inspection camera is placed into the branch line and pushed up to the main/branch interface. The function of the camera is to monitor the positioning process. Once the LCR-B packer has reached the junction, the mouth piece of the LCR-B hat profile or LCR-B liner can be turned by means of the locked air push rods for proper alignment with the branch. Then the LCR-B packer is slightly inflated via the LCR-B control box and the hat profile or liner is brought into its final position. After a brief time lag, the LCR-B packer will be inflated to start the inversion process of the LCR hat profile. After complete inversion of the LCR-B hat profile or LCR-B liner, the LCR control box is set to cure pressure to be maintained until final cure. After cure, a vacuum pump integrated in the LCR-B control box removes all air from the DrainLCR-B packer. Then the deflated packer can be removed with the help of the air push rods.

2. Installation Process

2.1 Introduce and push the LCR-B packer into the downpipe. The flexible LCR-B packer can be pushed through 45° bends (DN 100 or higher), or 90° bends (DN 125 or higher) down to the point of repair. A monitoring camera installed in the branch pipe helps the positioning process.

2.2 Position the LCR-B packer

For easier positioning, the installer pushes the LCR-B packer beyond the main/lateral interface while aligning the LCR-B hat profile with the lateral.

2.3 Bring the LCR-B packer into its final position

Pull back and turn the LCR-B packer to ensure the mouth piece of the LCR-B hat profile is centred to the branch opening

page | 5

2.4 Install the LCR-B hat profile

The inversion process is initiated as monitored by the camera placed in the lateral connection.

The inversion process is complete when the LCR-B hat profile has been fully inverted.

Set the LCR-B control box to the desired cure pressure.

2.5 Remove the LCR-B packer

Remove the air from the LCR-B packer using the vacuum pump integrated in the LCR-B control box. This deflation process separates the LCR-B packer entirely from the LCR-B hat profile and allows the packer to be safely removed from the line.

After use, clean the packer and check it for damages.

Summary conclusion The LCR-B system is used to repair and permanently seal main/lateral interfaces and laterals of downpipes or underground house sewers up to 1300 mm down into the lateral (standard = 280 mm). This is possible also by steam curing (epros®SteamGen V3/V6). The system can use either an LCR-B hat profile or an LCR liner. The LCR-B hat profile in the main pipe seals the interface between the two pipe systems with its rim only, whereas the LCR liner is designed as a part liner in the downpipe or house sewer. Application Main pipe: DN 100 to DN 200 Lateral: DN 50 to 200 at 30° to 90° Behaviour in bends Depending on the actual host pipe run or on wrinkles formed in the installed liner: 45° for DN 100 main line 90° for DN 125 or larger main line Wall thickness of 2 to 3 mm Result: Before

Benefits • Meets practical needs:

Successful repairs with little equipment needs only, even in the presence of bends.

• Price advantage: Low investment cost, because you need to buy just the packers actually required.

• Practical: The low-weight mobile unit with low space requirements can be placed even in a small car.

• Flexibility: The job can be done with air push rods; no carriage needed.

• Accessibility: The LCR-B packers can be folded as required.

• No risk of fire: The resin system used for the liner system is self-extinguishing.
